“How often does it occur that information provided you on morning radio or television, or in the morning newspaper, causes you to alter your plans for the day, or to take some action you would not otherwise have taken, or provides insight into some problem you are required to solve? For most of us, news of the weather will sometimes have such consequences; for investors, news of the stock market; perhaps an occasional story about a crime will do it, if by chance the crime occurred near where you live or involved someone you know. But most of our daily news is inert, consisting of information that gives us something to talk about but cannot lead to any meaningful action. This fact is the principal legacy of the telegraph: By generating an abundance of irrelevant information, it dramatically altered what may be called the "information-action" ratio.”
